Openings to experiment with #2

In club play I've recently come across the Tartakower variation of the Sicilian defense. This is a gambit which often arises from the move order of the "Smith-morra gambit", which is slightly different theoretically, although in most cases they reach the same positions very early. Initially I had a slight disdain for this opening (I'm one of those people who thinks almost all gambits are unsound and only useful if the opponent is unprepared), but after a few losses to it I began to give this opening a closer look.
